Answer:
The possible thickness of the soap bubble = 
Explanation:
<u>Given:</u>
- Refractive index of the soap bubble,
- Wavelength of the light taken,
Let the thickness of the soap bubble be 
.
It is given that the soap bubble appears very bright, it means, there is a constructive interference takes place.
For the constructive interference of light through a thin film ( soap bubble), the condition of constructive interference is given as:
where 
is the order of constructive interference.
Since the soap bubble is appearing very bright, the order should be 0, as 
order interference has maximum intensity.
Thus,
It is the possible thickness of the soap bubble.
Explanation:
The acceleration of an object depends directly upon the net force acting upon the object, and inversely upon the mass of the object. As the force acting upon an object is increased, the acceleration of the object is increased. As the mass of an object is increased, the acceleration of the object is decreased
Given :
An object with weight 20 N was lifted to 0.5 meters.
To Find :
How high must you lift a 25 Newton book for it to have the same increase in potential energy as the given book.
Solution :
Since both have same potential energy :
Putting all given values in above equation :
Therefore, book with same potential energy is at a height of 0.4 m.
The correct answer is A. The water at this conditions is in the solid phase. This can be verified by using a phase diagram. A phase diagram is a figure which shows the phases of a certain substance at a specific temperature and pressure.
answer
no
Explanation:
I do not think that I would because even though its a conductor in the insulator I think it would insulate it before it will work (not sure if that makes sense)
